1解下列方程并检验.x+0.3=1.8 3+x=5.4 x-1.5=4 x-6=7.6
1解下列方程并检验.x+0.3=1.8 3+x=5.4 x-1.5=4 x-6=7.6

1解下列方程并检验.x+0.3=1.8 3+x=5.4 x-1.5=4 x-6=7.6
x + 3.2 = 4.6
x = 4.6 - 3.2
x = 1.4
x - 2 = 15
x = 15 + 2
x = 17
x + 0.3 = 1.8
x = 1.8 - 0.3
x = 1.5
3 + x = 5.4
x = 5.4 - 3
x = 2.4
x - 1.5 = 4
x = 4 + 1.5
x = 5.5
x - 6 = 7.6
x = 7.6 + 6
x = 13.6
望采纳!

1.8 3+x=5.4 x-1.5
